Usage:     
Sodium Hypophosphite is often applied as reductant in electroless deposition of nickel (Nickel Chloride, buffers.) It builds complexes with the nickel in the bath, improving the fineness of the surface after treatment.

Storage:     
Store in a cool, well-ventilated area. Keep away from ignition sources, heat and flame. Store in tightly closed container. Incompatibilities: oxidants and food.
